Value that Semlon products create for you

Power and maintenance account for 52% of the total cost of a pump from purchase/installation to operation/maintenance to the end of its life.

If a 7-stage vertical pump with a rated power of 68.9KW, 380V/50Hz, 2950 RPM and a BEP flow rate of 100m3/h is equipped with a Semlon 6000 impeller ring, it can save 43,490 Yuan of electricity fee per year.

(Based on the price of industrial electricity at 0.8 Yuan / kWh)
